MACHINE E'G F PIG' IRON MGLDS.

[A im m n i 1 w Y i in E conical )art `lr, has also a central square hole identicall with the square holes ol'V the sections ol'l the roller, and revolves therewith together with the shalt Referring to all the similar sections which comprise the spiral roller M, and which is cleartxr shown in Figs. and t oll the drawing, are, when together, parallel and l'orni a continuous roller with spiral pig iron mold l'ornlers T.

The upper part ol the roller M, together With the collars, or flanges T, partially around the same as formcrs oll pig iron molds, and as shown in Fig. 5) of the drawing, has a flared groove 5, which extends from end to end of the roller, and divides the flanges T. The groove 5 forms a transverse bank of sand (i, on the sand loorwh as shown in Fig. lof the drawing.

The groove 5 is shown on the top part of the roller in all the views of the drawing. The roller M from the bottom of the groove 5 is the nearest part of the roller to the center of the shaft N of the roller, and the top of the groove 5 of the roller is the greatest distance of the roller fron] said center of shaft, the roller gradually widening outward in spiral form between the two parts referred to and shown in Fig. 3 of the drawing. The flanges T of the roller follow in parallel form the exact contour of the roller and extend therefrom the same distance in the same spiral form as the roller, shown in said Fig, 3 of the drawing. The lower part of the roller has a bar S rounded on its outer parts and which extends from end to end of the roller and continues on the conical part 1, of the roller. The bar S is to form the sow or transverse feed passage 9 in the sand at every revolution of the barrel M. The flange T, at the, bar S divided and apart to form an opening 10 in the flanges T, one side of said opening being the commencement of the mold or formation of the mold in the sand and the opposite side of the opening is the termination of said mold. It will be noticed that the bar 8 does not project from the barrel M, as far as the flanges T, this feature is to facilitate the complete ruiming off of the molten metal from the sow 9 and into the pig iron molds 12 in the sand and shown in Fig. 1 of the drawing.

The flanges T in every operation form the pig-lron molds 12, 1n the level sand W, which is formed and leveled by the roller M. The pig-iron molds l2, are the same depth and breadth of the flanges T, and the length of the molds are the saine as the length of said flanges T from the groove 5, to the opening 1U.

1t will be noticed that the spiral form of the barrel M varies the same the incline of the track A in the same length of track and circumference of the barrel, in order to roll the sand floor level as shown in Fig. 2 of the drawing. The level of the fioor is important, so is the level of the pig-iron molds 12 which are lornied level hy' the spiral form of the Ilange T. As the carriage (l travels downward on the track the barrel M, together with its nlnnher olI [langes 'l` decret-rse in radial lille from the center ol' the shaft N, thereby producing a level .sand floor, and level pig-iron lnelds.

()ne end ol the pig-iron molds aujoin the transverse sand bank (i, which is formed in the sand loor by the dividing slot .5, in the barrel, and the opposite ends of said molds adjoin and cominunicate with the transverse sow, or passage S), which is formed in the sand floor by tht.` har H, and the opening 1U, in the ianges T, of the barrel.

The channel former P, referred to, forms the channel 13, which is parallel with the track A, and on the same incline as the track and the upper end part of the channel 13 receives the molten iron from a cupola, or iron 1n elting furnace and runs down the charniel l.

Then the molds are formed in the sand Iloor, as described, there is a parallel bank of sand 15 formed between the channel 13 and the transverse feed passages t), and extends the length ofthe travel of the roller, and opposite to each said formed feed passage the sand is removed by hand, in order to make a passage 16, in the sand tioor to connect the channel 13 with the feed passages tl.

The operation of the machine is as follows: The carriage (l is placed in position on the higher end of the track A, and when brought down grade on its carrying track wheels l), the shaft .ll and its fingers li revolve together by means of the spur wheels F and J on their shafts E and H respectively. The fingers K prepare the sand floor lV, in advance of the roller M, which rolls on the prepared floor at the same time and levels the tioor as sliown in level lines lV in Fig. 2, of the drawing. At this time the independent channel former l?, rolls on the Hoor and forms the channel 13, and' the flanges T of the roller M, form the pig-iron level molds 12 on each side of the bank of sand G and disconnected from said bank, and the opposite ends of the level molds 12, connect With the sow or feed passage which is formed by the bar or extension 8 of the roller and the openings 10 of the flanges T. The molten iron passage 1o from the channel 18 to the feed passages E) is formed by hand. The molten metal when poured into the upper end part of the channel 13 runs therein and passes through the passage l 1G and thence into the pig-iron molds 12.

Each pig-iron when molded is separated and the ends of said irons are easily broken when cooled from the sow U.

What I claim as my invention and desire to secure by Letters Patent is 1. In a machine for forming pig iron molds, an incline track, a carriage adapted to run on the track, a transverse shaft ournaled in the carriage, a spiral formed roller on the yIOC shaft and adapted tra mll level floors nl sand by the lxfl nl the Carriage, a Clml'lnvl furni- P um? to one and uf th@ shaft, means fm tin rollor to frm a transverse bank ul' sand, 'moans on the mler t funn a mnsvi'so l'evd passing@ and Hwang @n th? rolm tu form molds fr pig-iron on tlm sides of the fe'd pssages Rnd mmmuuicutng thermvih.
